“…This low activation (< 21% MVIC) of the biceps femoris is related to 90 • knee flexion in the suspended supine bridge. Ho et al (2020) found a similar low activation (18% MVIC) of the biceps femoris in the dynamic supine bridge (90 • knee flexion). However, the effect of WBV in the static supine bridge, maintaining the 90 • of knee flexion, elicited a significant moderate activation (21-40% MVIC) of the biceps femoris at 30 Hz and 50 Hz, although the non-vibration condition also showed a moderate level of activation (27% MVIC).…”

Traditionally in strength and conditioning environments, vibration has been transmitted using platforms, barbells, dumbbells, or cables but not suspension devices. This study aimed to examine the effects on the lower limb of applying superimposed vibration on a suspension device. Twenty-one physically active men and women performed supine bridge and hamstring curl exercises in three suspended conditions (non-vibration, vibration at 25 Hz, and vibration at 40 Hz). In each exercise condition, the perceived exertion scale for resistance exercise (OMNI-Res) was registered, and the electromyographic signal was assessed for gastrocnemius (medialis and lateralis), biceps femoris, semitendinosus, gluteus maximus, and rectus femoris. A linear mixed model indicated a significant fixed effect for vibration at 25 Hz and 40 Hz on muscle activity in suspended supine bridge (p < 0.05), but no effect for suspended hamstring curl (p > 0.05). Likewise, the Friedman test showed a significant main effect for vibration at 25 Hz and 40 Hz in suspended supine bridge (p < 0.05) but not for suspended hamstring curl (p > 0.05) on OMNI-Res. Post hoc analysis for suspended supine bridge with vibration at 25 Hz showed a significant activation increase in gastrocnemius lateralis (p = 0.008), gastrocnemius medialis (p = 0.000), semitendinosus (p = 0.003) activity, and for semitendinosus under 40 Hz condition (p = 0.001) compared to the non-vibration condition. Furthermore, OMNI-Res was significantly higher for the suspended supine bridge at 25 Hz (p = 0.003) and 40 Hz (p = 0.000) than for the non-vibration condition. Superimposed vibration at 25 Hz elicits a higher neuromuscular response during the suspended supine bridge, and the increase in vibration frequency also raises the OMNI-Res value.

“…Because the knee angle was limited to 90 degrees in this experiment, hamstring activation was decreased, and the activation of the gluteus maximus was increased. Previous studies confirmed that activation of the hamstring decreased with increasing knee flexion angle [45,46], and when the movement was performed in the same range of motion, decreased activity of one muscle can give rise to increased activity of another muscle to achieve the same range of motion [11]. Thus, it is thought that the increased activity of the gluteus maximus reduced the activity of the biceps femoris.…”

PURPOSE: This study examined the effects of the resistance levels on the muscle activities around the hip and spine during bridge exercise with hip abduction resistance in patients with chronic back pain. METHODS:A cross-over study design was used. Twenty subjects with low back pain were enrolled in this study. The subjects performed bridge exercises with hip abduction resistances (20 mmHg, 40 mmHg, and 60 mmHg). A Narrow Sling was used to provide resistance. Surface electromyography was used to measure the activity of the erector spinae, biceps femoris, gluteus maximus, and gluteus medius. RESULTS:The muscle activity of the gluteus maximus and gluteus medius increased significantly with increasing resistance levels. There was a significant difference in the †Corresponding Author : Myoung-Kwon Kim

“…The posture of bridging exercise has a lower-body centre of gravity and a larger base of support than that of the repetitive sit-to-stand tasks. Bridging exercise strengthens muscles around the hips [13][14][15] and knees. 13,16 The improvement in the hip and knee muscles strength in the affected lower limb may contribute to weight-bearing, then promotes sit-to-stand function.…”

Objective To examine the effect of a progressive bridging exercise on force, time, and pressure during the extension phase of sit-to-stand, and on sit-to-stand ability in individuals with stroke. Design A single-blinded randomised controlled trial. Setting Hospital. Participants Forty-eight individuals with acute ischemic stroke, not at brainstem and cerebellum, randomly allocated to the intervention ( n = 24) and control ( n = 24) groups. Five participants dropped out during the 2-month follow-up, but they were in the intention-to-treat analysis. Interventions The intervention group undertook a 45-min conventional physiotherapy and a 30-min progressive bridging exercise. The control group received only the conventional exercise. Main measures Peak vertical ground reaction force, time to peak force, peak foot pressure, and regional peak foot pressure during the extension phase of sit-to-stand, and sitting-to-standing item of the Motor Assessment Scale were assessed before training, after 4-week training, and 2-month follow-up. Results The intervention group showed significantly ( p < 0.001) less difference in peak vertical ground reaction force between feet during the extension phase of sit-to-stand than the control after 4-week training (mean ± standard deviation; intervention, 5.38 ± 3.99; control, 17.1 ± 10.3) and 2-month follow-up (intervention, 6.79 ± 3.84; control, 17.5 ± 9.89), and demonstrated significantly ( p < 0.001) higher score in sit-to-stand than the control after training [mean (interquartile range); intervention, 5 (2-5); control, 2 (1-2)] and follow-up [intervention, 2 (2-5); control, 2 (1-2)]. Both groups demonstrated peak foot pressure on the medial and lateral heels, metatarsals, and hallux regions. Conclusion Progressive bridging exercise improved symmetrical weight bearing during the extension phase of sit-to-stand, consequently enhanced sit-to-stand ability in individuals with stroke.
